After Oceanic Air flight 815 tore apart in mid-air and crashed on a Pacific island, its survivors were forced to find inner strength they never knew they had in order to survive. But they discovered that the island holds many secrets, including a mysterious smoke monster, polar bears, a strange French woman and another group of island residents known as The Others.
